pause-spotify: Don't launch Spotify if not running

[henrik]

You can verify with

osascript -e 'tell application "Spotify" to pause'

that the old version of the command will launch Spotify if not already running.

Thanks for your contribution, @henrik! 🎉

We've done some automated sense checks on your trigger, pause-spotify. All looks great! Someone from Tuple will now manually review your trigger's code and get back to you.
